Automatic detection of impact craters on Al foils from the Stardust interstellar dust collector using convolutional neural networks
Logan Jaeger, Anna L. Butterworth, Zack Gainsforth +9
NASA's Stardust mission utilized a sample collector composed of aerogel and aluminum foil to return cometary and interstellar particles to Earth. Analysis of the aluminum foil begi…
Fine-grained Material Associated with a Large Sulfide returned from Comet 81P/Wild 2
Zack Gainsforth, Andrew J. Westphal, Anna L. Butterworth +10
In a consortium analysis of a large particle captured from the coma of comet 81P/Wild 2 by the Stardust spacecraft, we report the discovery of a field of fine-grained material (FGM…
Measurement of the Oxidation state of Fe in the ISM using X-ray Absorption Spectroscopy
Andrew J. Westphal, Anna L. Butterworth, John A. Tomsick +1
The oxidation state of iron in the interstellar medium (ISM) can provide constraints on the processes that operated on material in the protosolar disk. We used synchrotron-based X-…
Atomic Layer deposition of 2D and 3D standards for quantitative synchrotron-based composition and structural analysis methods
Nicholas G. Becker, Anna Butterworth, Andrey Sokolov +5
The use of Standard Reference Materials (SRM) from the National Institute of Standards and Technology (NIST) for quantitative analysis of chemical composition using Synchrotron bas…
Oxygen Isotopic Composition of Coarse- and Fine-grained Material from Comet 81P/Wild 2
Ryan C. Ogliore, Kazuhide Nagashima, Gary R. Huss +3
Individual particles from comet 81P/Wild 2 collected by NASA's Stardust mission vary in size from small sub-m fragments found in the walls of the aerogel tracks, to large fragme…
